Few month old monitor showing horizontal lines

[xDanielxOossiex]

This is the best picture I could get

both monitors are the exact same model and they were bought on the same day. On the right is the monitor without issues, and the one on the left has the horizontal lines. Also the text on the left display looks "glitched" or something

 

I already did this to try and fix it:

- Downgraded to an older display driver

- Swapped cables to see if it was cable/gpu output related

- Changed the display settings in windows

 

Is there anything else I can try before I have to take it to the store and get a new one?

If the monitor has another input maybe try that instead. 

 

If the power supply are external from the monitors (aka the cord has a brick) maybe try swamping the monitor power cables around.

 

Both of these are kind of long shots, and you would still have defective hardware even if they do fix the problem.
